lb all whom it may comem:

Be it known that I,- Fnnnnrcx M. SADLER, a 'citizen of thelUnited States' o/f America, residing at lEllsworth, in the county of Nobles and Statepof Minne'sotznlhaveinvented .certain new and4v useful Improvements in 1mb. said stub-axle is 4mehr provided Steering Mechanism, of whichcthe; follQW- ing. is a specification.l l'

This invention relates, 4to vsteering-axles for motor driven velncles and,'.more particularly, to that class of Vaxles inA which lthe wheels are individually-pivoted to the axle The object of myinventionfis to :provide a simple and ecient structure in Iwhich the pivot point lies withinythejcentralplane of the wheel, thereby 'doing away with lthe tendency of the wheel .to-veer when an obstruction is met with. l i' A further object of my structure isv to provide a dust proofand easy running c'onnection between the wheel` and its axle.

In the drawing, which represents a longitudinal sectional view of the invention, a main axle 1 terminates in a spherical head 2 provided with a recess 3 for the reception of the pivot pin 4or bolt 4 which holds the stub axle in lace. A stub-axle 5 provided with a cup shaped recess y6, said recess terminating at its 'bottom "in a hemisplierical recess 7,' for the reception of the spherical ,end of the axle,.terminates at its inner por- -tlon in the outwardly flaring'flange 8 provided with ari annular recess 9 for the relceptionl of projection or flanve 10 of the with a suitable recess 11 for the reception of pivot'pin 4 and, at itsouter end2 with the threaded recess 12 for the reception of the tap bolt 13 which holds in place the' ball. retaining Washer 14.

' As is suggested in the drawin the stub l vaxle 5 may be.I centrallybored t roughout its length and such bore threaded. .The

head 2A of axle 1 in this form of the invention has an end recess that is .engaged by a projection on a lwasher 15. Aspring 16 in the bore holds washerl in ielding engage'-4 `ment with" axle head 2 an the tension of the spring may be regulatedb the screw 17 that engages the threads of t e stub axle bore. A tap bolt may be used to seal the outer end of the stub axle bore.

4With the structure just described, it will be clear that the pressure of the washer 15 on the'axle head 2 yieldably op oses pivotal movements of the stub axle, suc opposition to the pivotal movements of said stubaxle being sufficient to prevent accidental wab'- bling of the wheel such as would be incidental to wear of contacting parts, and the like.

The stub-axle is further provided with I an arm 18 to which is pivoted'the connecting rod between Wheels, and Withthe arm 19 for connection with the steering rod.' The wheel'hub 2O hasa cup shaped recess to accommodate the form of the stub axle and is .provided with suitable ball-races 21v for the bearing and,the`pivot point lying in the central plane of the wheel, there is no sidewise thrust due to the `wheel coming in contact with obstructions. j

Having described mylinvention, what I Claim as new and desire to secure by Letters Patent, is

1. A steerin mechanism for vehicles comprising an ax e terminating in a head2 a stub axle having a center bore into wlnch the head projects, means for pivotally connecting the head t0 the stub axle, a washer in the bore and adjustable means for adjustably holding the washer in engagement with the head to oppose pivotal movements of the stub axle.

A steering mechanism for vehicles com- Erislng a main axle, a 'stub axle having a orev lnto which the main axle projects, means for pivotally connecting the main axle to the stub axle, a washer 1n said bore and engaging the main axle to oppose pivotal movements of the stub axle relative to the main axle, and means for maintaining a yieldable pressure on said washer.V

3. A steering mechanism forvehicles comprismg a stub axle having a central bore, sald bore being threaded, a main axle having an end head projecting info the bore, tension of the spring, and a closure foi1 the said head having an end recess, means for outer end of the bore. 10

pivotally connecting the head to the stub In testimony whereof I herennto aiiX my aXle, a washer in the bore and provided signature in presence of two witnesses. with a projection that enters the recess in A v FREDRICK M. SADLER. the head, a spring in the looreV foryeldably Witnesses:

holding the washer in engagement with the F. W.' STANTON,

head, a screw inthe bore for regulating the E. A. NELSON.
